BRICK-DRYING APPARATUS.

Application filed March 6, 1917. Serial No. 152,507. 1 I

To all whom it may concern:

Be it known that I, EDWARD J. MOORE,

citizen of the- United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio,-have invented certain new and useful Improvements in Brick-Drying Apparatus, of which the following is a specification.

This invention pertains to a brick drying apparatus constructed and adapted to operate substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of the main portion of theapparatus broken out at thecenter and Fig. 2 is a'sectional elevation, enlarged, of the intake end of one of the several series of roller carriers for the bricks seen one above the other in Fig. 1. 20

Fig. 3 is a side elevation of the portion of the apparatus shown in Fig. 1, but on a greatly reduced scale, and Fig. 4 is a plan view of Fig. 3. Y

- Fig. 5 is a cross section of the upper half of the parts shown in Fig. 1. Fig.6 is an elevation of the elevating mechanism at the tail of the drier, and Fig. 7 is a plan view of Fig. 6. f

.Fig. 8 is a sectional elevation lengthwise of a modification of the apparatus, but which also may be the preferred form thereof, and showing the respective ends with the body of the drier broken out at the middle. Fig. 9 is a sectional plan of Fig. 8, as hereinafter more fully described.

The plan of the invention as thus disclosed in the drawing contemplates the drying of bricks in a suitably large chamber adapted to receive the bricks at one end and to discharge them at the other in a dried state and which is sub-divided lengthwise Thus, the drier chamber or drier proper is shown as suitably inclosed its full length and width by a wall 03 made of sheet metal or other material and divided lengthwise from top to bottom into a series of spaced drying chambers or subdivisions separated by intervening horizontal walls 2 of sheet metalextending from side to side and end to end of the drier andclosed their entire length and width to prevent open communication between chambers, or, to be more definite, to provide for separating drying of the bricks in each chamber according to the conditions therein and independent-of other related chambers. 7

Each chamber is provided with a series ofrollers 3 along each side portion and supported on suitable brackets from the floor of the chamber and adapted to convey the platens or plates 4 on which the bricks b are delivered to the drier from or by the elevating and delivery mechanism, as by endless carrier '5, Fig. 1, or the elevating their plates 4 by carrier 5 the plates in ad- Vance or first delivered into the said chamber will be fed by gravity or by a cable conveyer until the said chamber is filled between its ends. Then the chamber is closed and the carrier 5 lowered to the next lo chamber in the guideways g at the res .1 tive sides and end of the drier, the sha ts 8 being extended through said guideways at each side and having a drum 7 mounted thereon and supporting said carrier. The dotted line below in. Fig. 1 shows the lowest level of the carrier for delivery purposes, and all the subdivisions or chambers are alike in all their equipments, and each chamber has a swinging or hinged gate or door 8 at its entrance adapted to close automatically or to be closed by hand when the chamber is full and the drying proceeds. Screw or'worm or other suitable mechanism is employed to-raise and lower shaft 8 of the carrier in said guideways, but in Fig. 3 I show a counterweight w and a cable running over sheaves for this purpose.

The invention. contemplates the use of heated air for drying the bricks, and to this end I provide a suitable hot air duct 9, Fig. 3, at the rear end of the drier extending downward from a heating chamber 10 or other source of heated air and which duct has inlet openings to the respective drying chambers. At the opposite or front end of the drier I provide another duct 12, which likewise, is open to the respective drying chambers by successive openings thereto and which communicates with an exhaust fan or blower f, by which the air and moisture are exhausted through and from said chambers. Suitable dampers or other means may be employed to control the air entering each chamber, and'it is not intended to close off any chamber from exposure to the drying downwardly inclined to provide gravity air except in charging and discharging operations.

itt'he rear end of the drier there is provided a receiving device for the bricks on their plates or platens 4, shown in elevation Fig. 6 and consisting of two endless carriers 14 havin ledges or shelves 13 at intervals on their inner sides to rest the platens upon and mounted on drums or rollers 15 fixed on shafts 16 and operatively connected to travel together by means of the connecting bevel gears 17 on shaft 18, Figs. 6 and 7 and which shafts are suitably supported at their ends in the frame work of the structure. Power is communicated to the shaft or shafts 16 through sheaves 20 thereon, and means are provided at the end of the drier to deliver the platens with their bricks upon said carriers 14 and by which they are successively lowered to be taken awayjn their dried state. The hinged dro doors 11 at the ends of the drier chambers ridge the intervening space to the said endless carrier 14 and are. adapted tobe turned down and provide atransfer over which the platens are delivered.

Figs. 8 and 9 show a modification of the invention in which there is an endless carrier at each end, of like construction in all essential particulars and both having end-v less chains 25 running over sprocket wheels 26 and equipped at intervals with intervening suspended carrier members -28 and 28 adapted each to receive one of the platens 4, either for delivery to the drier at the receiving end or for discharge therefrom at the delivery end. Doors 30 also are shown at the entrance to each chamber and which are adapted to be turned downon their spring lift hinges and carry rollers 31 adapted to receive the platens from the carriers and the platens are delivered to the said carriers 28 from the delivery rollers 33, Fig. 9, and the opposite corresponding rollers 34 supported to turn down from the carrier frame 35 and from which rollers the said carriers 28 pick upthe platens with their loads of brick and carry them around to receiving position on the doors 30 to enter the drier chambers.

At the opposite or discharge end of the to the cable.

drier I show drop doors 30 having rollers 31 and opposite these are the pivoted supports 37 with rollers 36 and adapted to coopcrate with the drop doors 30 in receiving the discharge of the platens when this point is reached, andthe rollers 33 and 30 at the receiving end may be inclined inward and downward in like manner to gravitate the loaded platens onto the rollers 44 by which the platens are impelled through the chamber as drying proceeds. At both the front and the rear of the drier the said end or drop doors are pivoted or hinged on suitable supports, and shaft 46 is in power relations at one end by miter gear arrangement 4.7 with driving shaft 48 running lengthwise of the drier at the outside thereof, and which has other miter gear connection with the shafts 50 that carry the sprocket wheels 26 and 26..

Fig. 9 discloses means for positively driving rollers 44 which carry the platens or plates 4, the power being applied through each counter shaft 46 and suitable .cords or cables 49 in running engagement with the said rollers and the sheaves 51 horizontally disposed at the respective sides of the drier chamber and the sheaves 51 are on the outside of the drier and mounted on a bracket 52 which is made adjustable to apply tension What I claim is:

1. A drying machine as described, having a series of compartments one above the other and closed between their ends, separate inlets and exhausts at the respective ends in each chamber for the drying agent,

same and in line with the rollers on said doors.

3. A drying machine having a series of compartments one above the other lengthwise and closed between their ends, means at one end of said compartments adapted to deliver the material thereto successively and separate doors at the ends of said chambers respectively, adapted to bridge the delivery of the material to the chambers.

4. In a drying apparatus as described a less carrier. at the other end to receive the f dried material and a door at the end of each chamber adapted to coact with said carriers in the transfer of the material.

6. A drying machine as described, a drying chamber having doors at its ends adapted to be swung down and form means by which wise having separate hinged doors at their ends adapted to bridge the introduction and discharge-of the material to be dried, in combination with means at one end to supply the material to said chambers successively and means at the other end to discharge the material therefrom and the means at both ends operatively related with said doors. Y

8. A brick drying machine, comprising a series of separate elongated chambers in superposed relation having independent brick carrying means lengthwise therein, means to circulate heat through each chamber independent o'fthe others, and means to charge and discharge said chambers singly while circulating the heat through one or more of the remaining chambers.

9. A series of superimposed brick drying chambers having separate heat circulating inlets and outlets and means to control the same, brick carrying means extending lengthwise of each chamber, and charging and discharging devices at opposite ends of said chambers.

Signed at Cleveland, in the county of Cuyahoga, and State of Ohio, this 29th day of January, 1917.
